Weather Center Advanced Use

How Does It Work?

The custom graph feature needs to be updated for new graphing system.

Thanks for your patience.

How does it work?

The Advanced use of the Weather Center allows one to create a custom view that shows the
graphs for specified time frame and graph interval. This is useful if you want to 'zoom-in' and see the data with more detail (at a higher
resolution).

If you are familiar with the Weather Center, you know that the 4 graphs have a 24 hour view and a 12 hour (8am to 8pm) view.
The graph interval (time between data points) is always 15 minutes. The custom view allows you to view the graphs say from 10am to 2pm with
a graph interval of 5 minutes.

The custom view is only available for current (today's) data. For more detail on a historical date, download
the raw 1-minutes observations from each day's history page.

To create a custom view, you just add the information to the URL and the view will be created.
The format is simple and the best thing to do is to copy an example and change it. Technically, the information added to the URL, are called
query parameters.

https://windpowerweather.com/custom?start=10am&end=2pm&interval=5

In the URL above, the custom view starts at 10am, ends at 2pm with a 5 minute graph interval.

The custom view will display the specified parameters and number of data points used to create the graphs. One must be careful not to
create too many data points which can cause a graph error. The Weather Center uses the Google Chart service and the requests
have a 16 KB limit. An error will be displayed if the request exceeds the limit.
